According to the present invention, a transparent inorganic thin layer is utilized as a refraction intermediate layer to allow each of first and second prisms to be formed on a base film of a prism sheet. Therefore, two additional prism sheets may be not used to reduce manufacturing costs and thickness, and simplify a backlight manufacturing process. Especially, a forward prism is configured to be formed on a bottom surface of the prism sheet. |
